Show the students a video explaining the development of animal cloning.The teacher explains the cloning development by means of video and encourages the students to speak English as much as possible. Then give some pictures to raise the students' interest. After watching the movie, I give the students the questions:Have you imagined the fierce and extinct animal such as dinosaur can be brought back to life? If students say that they would like with the dinosaurs. Then I can lead in the text .Now let's go into the text. I am sure you can get more information of that and you can get the answer to the question. Step3 reading Fast reading 1. The film Jurassic Park is popular because _____.

A. people are interested in the subject of cloning

B. all the actors are dinosaurs

C. it was directed by a scientist who clones dinosaurs

D. it proves very interesting

2. We can infer from the text that____

A. scientists are experimenting to clone dinosaurs B. dinosaurs will never return to the earth C. cloned animals will only live in the zoo D. the DNA of dinosaurs can only survive 10 000 year 3.The writer of the text_____

A. is excited by the possibility of cloning fierce and extinct animals

B. believes that extinct animals can be brought back to life by cloning C. thinks it impossible or unsuitable to clone extinct animals like dinosaurs

D. dreams of dinosaurs returning to the earth Careful reading Read the passage carefully and then answer the following questions. 1.Why shouldn’t you clone an extinct animal if there isn’t enough diversity in the group? There will not be enough genetic variation in the group to be able to resist new illnesses 2.Why is it wrong to clone an extinct animal if it would have to live in a zoo? Because it is not a suitable habitat to develop and increase its numbers. The zoo is not a natural environment for a wild animal. 3.Why can’t you clone the DNA of animals that have been extinct

longer than 10,000 years? The DNA of animals more than 10,000 years old is not suitable for cloning, for it can’t survive so long.
